Symptoms. - The attack comes on suddenly; the animal paws, looks at its sides, jumps up in the air and throws itself violently upon the ground, rolls upon its back and tries to balance itself there. In a case of purely spasmodic colic there is very little, if any, visible bloating, but it is often combined with flatulent colic, then there is danger of rupture of the stomach from its great distention with gas and the violent plunging together.
Treatment. - If there is no bloating, from one to two ounces of laudanum in half a pint of water will generally give relief. If there is bloating give the drench recommended for flatulent colic. In either case use the warm water injections freely. There is no danger of overdoing this part of the treatment, and I am satisfied that many cases will yield to hot water injections alone if applied in time. The physic, as used in flatulent colic, should also be given in spasmodic colic. After a case of colic, either flatulent or spasmodic, the patient should be allowed no grain for at least twelve hours and should be fed sparingly for two or three days.
When a dose of medicine has been given, due time should always elapse for it to take effect before another is given. The common habit of pouring down dose after dose, as fast as some new-comer on the ground recommends a new remedy, has killed many a good horse that might have recovered without any medicine if left alone.
